  Log:
    merge revision(s) 43609,43617: [Backport #8878] [Backport #9085]
    
    vcs.rb: split
    
    * tool/vcs.rb: split from file2lastrev.rb.
    * tool/rbinstall.rb (Gem::Specification.load): obtain spec date from
      VCS for the case using git, RUBY_RELEASE_DATE is the last resort.
      probably fixes [Bug #9085].
